Working Principal
Zest Bypass flow meters measure linear
fluid flow rates in conjunction with an
orifice
plate.
This
provides
an
inexpensive method of measuring flow
rates in pipes of two inch or larger using
relatively low-cost orifice plates. The
bypass flow meters consist of a mainline
orifice, a set of orifice flanges, a flow
meter. A secondary orifice and bypass
piping. A size 1/2” Metal Tube MT 3809
or Glass Tube Rotameter is used to
measure flow regardless of main line
pipe size. The purpose of the mainline
orifice plate is to create the pressure
differential. The secondary orifice is
sized such that the total pressure drop
though the bypass piping equals the
pressure differential across the mainline
orifice. Because the same pressure drop
exists across each line, the 1/2” flow
meter in the bypass line gives an exact
indication of flow rate in the mainline.
The Zest Bypass flow meter with its
secondary orifice is calibrated as a unit.
Main line differential pressure and
orifice practice data is available from
ASME, DIN and manufacturers of
primary
elements.
Because
the
secondary orifice controls the flow
through the bypass line, a change in
orifice
diameter
changes
the
differential ranges.

Installation Diagram
The achievable accuracy of the Zest Engineering
flow meter is a function of installation. For the best
results, a minimum straight length requirement of
10 diameters upstream and 5 diameters
downstream is recommended
